The invention utilizes an intermediate means which is attached to the mounting 'portion of the clipper, and which accurately may be positioned thereon by the clipper manufacturer. The stationary clipper blade in turn is positioned on the mounting portion by the intermediate means, and it may readily be removed and replaced by the ultimate user, the intermediate means being effective to insure that the stationary blade is replaced in the same position it occupied when it left the factory.

The Shanks of screws 28, as in the case of screws 25, are small in size compared with the openings 22 through which they extend, as best shown in Fig. 3. The screws 28 are the ones which secure stationary blade 20 to mounting portion 12 and which may be withdrawn by the. ultimate user when it is desired to remove blade 3 20 for cleaning or other maintenance. When blade 20 is replaced by tting the central openings 22 over the factory positioned cylindrical members 23, the screws 28 are reapplied and tightened to secure the blade. Such blade removal and replacement can occur an indefinite number of times without disturbing the critical factory positioning.

Referring to Figs. 4 7, a modied form of the invention utilizes a plate 3d) (Fig. 7) as the intermediate means. Plate 3l) has spaced openings 31 therethrough, and it is secured to mounting portion 33 of the clipper by means of headed screws 34. Openings 31 are large in size compared with the shanks of screws 34 which pass therethrough.

The forward edge of plate 30 is irregular in shape, and

v in the form shown has a pair of forwardly extending protuberances or lugs 36.

A stationary blade 38 has a rear edge which matches the irregular forward edge of plate 30, and the two edges abut, as shown in Fig. 5. Thus, the rear edge of blade 38 has recesses which receive lugs 36, thereby fixing the position of blade 38 with respect to plate 30.

Blade 38 has spaced openings 40, and headed screws 41 extend through the openings into threaded relation with mounting portion 33. Again, the Shanks of screws 41 are small in size compared with the size of openings 40.

In this modified form of the invention, plate 30 is positioned by the clipper manufacturer and screws 34 are tightened more or less permanently. Removal of stationl1 ary blade 38 is accomplished by removing screws 41, after which the blade may be replaced by reapplying screws 41. Plate 30 with its irregular edge, of course, is effective to insure that blade 38 is replaced in proper position relative to the movable clipper blade.

From the above description it is thought that the construction and advantages of my invention will be readily apparent to those skilled in the art. Various changes in detail may be made without departing from the spirit or losing the advantages of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
